The present invention relates to a harvester which is particularlyintended and designed for harvesting various kinds of peas and has forsome of its objects to provide,

in a manner as hereinafter set forth, a niachine of this character whichwill be simple in construction, strong, durable, highly etticient andreliable in use, light in weight, compact, adjustable and which may bemanntactured and operated at low cost.y

All of the foregoing and still 'further objects and advantages of theinvention will become apparent from a study of the tollowingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate'corresponding partsthroughout the several views, and wherein'z- Figure 1 is a view in topplan, showing a harvester construct-ed in accordance with the presentinvention.

Referring now to the drawings in detail, it will be seenv that theembodiment of the present invention which has been illustrated comprisesa traine which is designated generally by the reference numeral 1, saidframe including longitudinally extending, oppositely bowed pairs of bars2 between the end portions of which extend transverse bars 3. 'llhetraine 1 tui-'ther includes a transverse bar ht which projects laterallyfrom the lowermost of the inner pairs of bars 2. [i tongue 5 ispivotally connected, as at G, to the frame 1 Jfor s\ yinging movement ina vertical plane.

The frame 1 is mounted for vertical adjustment on a inain wheel 7 and acomparatively small wheel 8. The wheels 7 and 8 are adjustableindependently of each other. The main wheel .7 is journaled on an axle 9having its ends journaled in drums 10 which are operable verticallybetween pairs of spaced, parallel bars 11 which extend between the outerpairsl of bars 2 of' the trame 1. Thus, the inain wheel 7 is mounted inthe frame 1. Gears 12 are provided on the drums 10 and are operativelyengaged with racks which are provided 'therefor in channels in one ofthe bars 11 of each pair of said bars 11. The other bar 11 of each pairis provided with a guide channel for accommodating the gears 12. Cables13 are trained over suitable pulleys on the lower portion ot the frame 1and have one end connected to the drums 10 for winding on said drums.The other ends of the cables 13 are connected to drunis 1l for wint ingthereon, said drums 14 being fixed on a transverse shaft 15 which isjou-rnaled On a rear portion ot the frame 1. A hand lever 1G is providedfor actuating the shaft 15 for rotating the druins 10 through the mediumof the cables 13 for raising or lowering the frame 1 relative to themain wheel 7.

Rising from the free end portion of the transverse bar Llot the frame 1is a standard 17 having an opening 18 extending vertically therein Jrornits lower end in which a block 19 is mounted for vertical adjustment.The

vertical side edges of the block 19 are grooved to receive tonguesconstituting the vertical Walls of the recess 18. rlhis is illustratedto advantage in Figures 3, 13 and 14 of the drawings. Projectinglaterally from the block 19 is a spindle 2O upon Whichthe Wheel 8 isjournaled. Aneye 21 is anchored on the block 19.

Mounted on the bar 4 of the frame 1 and extending rear-wardly therefromis a horizontal, endless apron 22. rlhe apron 22 is mounted transverselyon the machine and is supported at its rear by an arm 23 having one ,endportion fixed on the rear end portions of the inner pairs of bars 2 ofthe frame l, saidjarni 23 having a down-turned end portion secured tothe frame of the, apron 22, as at 24. A cable 25' is trained oversuitably arranged guides, as at 26 and 27 (see Figures 3 and 11) and hasone end secured to the eye 21 011 the block 19. The other end of thecable 25 is secured to a--hand lever 28 Which is mounted for swingingmovement on an intermediate portion of the arm 23. As will be apparent,the cable 25 and lever 28 constitute means for adjustingthe block 19vertically in the opening 18 of the standard 17 for raising and loweringthe machine'on the Wheel 8. The lever28, of course, is yprovided Withsuit-able means, as at 29, for securing said lever iny adjustedposition. An operators seat 30 is also mountedonthe Varm 23.`

The reference numeral 31 designates a shaft which is mountedtransversely in bearings provided therefor on the inner pairs of bars 2of the frame 1.y These bearings-'are indicated at 32. The shaft 3lisprovided With a free port-ion upon Which isV journaled a sleeveY 33(see Figures 1 and 10) from one end of which an arm 34 projects. Acomparatively long arm 35projects from the other end portion of thesleeve. 33. The reference numeral 36 designates an arm which is similarto the arm 34 and which is pivotally mounted, as at 37, on the `upperportion of the standard-17.` An arm 38, similar to the arm 35, projectsfrom the hub or sleeve 37 of the arm 36. The free end portions of theAarms 34 and 36 areprovided With transversely aligned bearings in whichthe shaft 39 of a reel which is designated generally by the referencenumeral 40 is journaled.

The reel 40 comprises spiders 41 whichare fixed on theV endportions ofthe shaft 39.

Shafts 42 are journaled in the free end portions of the arms of thespiders 41 and Ahave projecting therefrom series of fingers 43. Looselymounted on theshaft 39 adjacent the innermost spider 41 of the reel 40is a gear 44 having a laterally projecting hub portion 45 in which thefree end of the comparatively long arm of a substantially U- l shaped,resilient lever 46-is anchored. The

llever 46 is engageable. selectively in vertically spacednotches 47which are provided therefor in a vertical bar 48 which rises from thebar 4 of the frame l. The notches 47 are shaped to receive and retainthe resilient lever 46, as illustrated to advantage in Figure 5 of thedrawings. As Will be apparent, the lever 46 provides means for rotatablyadjusting the gear 44 and for retaining said gear in adjusted position.Gears are fixed on the inner ends of the shafts 42 of the reel 40 andare operatively connected to the gear 44 by intermediate gears 50 whichare rotatably mounted on the innermost spider 41. It will thus be seenthat when the reel 40 is rotated, the shafts 42 of said reel will bevcaused yto rotate in the spiders 41 through et connectionl 52 to themain'wheel 7l for.-

actuation thereby. A Vchainfand sprocket connection 53 operativelyconnects the shaft 31 tothe main shaft 51. Then, a chain and sprocketconnection 54 operatively connects thev reel shaft 39 to the shaft 31'for actua-' I;

tion thereby. It Will thus be seen that the reel 40 is driven by themain Wheel 7. If desired, a suitable clutch may be interposed at anydesired point in the reel driving mechanism for disconnecting the reelfrom the'` i Wheel 7.

The. reference numeral 55 designates a "grooved pulley` Which isrotatably mounted on the arm 23 adjacent the hand lever 28.

A hand lever56 is fixed on the pulley 55 for-'f1' manually rocking saidpulley and, as best seen in Figure 12, said hand lever is provided Withsuitable means, as at 57, for releasably securing the hand lever inadjusted position. Itfwill be notedthat the pulley 55 and the hand lever28 are journaled on a common pivot pin 58 which passes through the arm23. Further, the latching means 29 and 57 for the levers 28 and 56 areidentical. Cables 59 have one'end secured to opil posite sides of theperiphery of the pulley 55 for Winding on said pulley. The cables 59extend in opposite directions from the pulley 55 over suitably arrangedguidesand pulleys 60 and have their other ends con- -'li nected to thearms 35 and 38. It will thus be seen that when the lever 56 is actuatedto rock the pulley 55, the arms 34 and 36 will be swung to raise 'orlower the reel 40.

The reference numeral 61 designates a shaft which is journaledlongitudinally on th-e frame 1, said shaft being Aconnected to the mainshaft 51 for actuation thereby through the medium of beveled gears 62. Achain and sprocketl connection 63 operaend of the angular lever f forreleasably securing tively couples the shaft 61 to the apron 22. Thereference numeral 64 designates a cutter bar which is mounted on theforward side of the bar 4 of the frame 1. A pitman 65 operativelyconnects the cutter bar 64 to the shaft 61 for actuation by said shaft61. The reference numeral 66 designates an angular lever having anintermediate prtion journaled in a bearing 67 which is provided thereforon a forward portion of the frame 1. One end of the lever 66 isoperatively connected to the tongue through the medium of a link 68. Acomparatively long bowed link'69 operatively connects the other 66 to anintermediate portion of a hand lever 7 O which is pivotally mounted, asat 71, on a rear portion of the frame 1. A rack bar 72 rises from theframe 1 for engagement with the link 7 9 said link in adjusted position,thus retaining the tongue 5 in adjusted position. rIlhe referencenumeral 73 designates a brace for the tongue 5.

Briefly, the operation of the machine is as As the harvester moves overthe ground, the cutter bar 64 and the reel 40 are driven by the mainwheel 7 in the manner previously explained. rllhe rotating wheel 4()sweeps the pea vines over the cutter bar 64 which, of course, severssaid vines which are then deposited on the apron 22 which travels in thedirection indicated by the arrow in Figure 1 of the drawings. Aspreviously set forth, the position or angle of the fingers or teeth 43of the reel 40 at the time they engage the vines may be regulated asdesired by adjusting the gear 44. The machine may be adjusted verticallyon its supporting wheels 7 and 8 through the medium of the hand levers16 and 28, respectively. As also previously explained, the reel may beswung in a vertical plane for adjustment relative to the cutter bar 64through the medium of the hand lever 56 which is fixed on the peripheryof the pulley 55.

It is believed that the many advantages of a harvester constructed inaccordance with the present invention will be readily understood, andalthough the preferred embodiment of the invention is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.
